唯一可用的集合数据结构是向量栈、枚举和hash表。

The only available collection data structures are vectors, stacks, enumerations, and hash tables.

最后，我决定使用vec函数—它的速度相当快，对于处理dna而言，它无疑是正确的选择(本质上，DNA是个位向量，一个内建的Perl数据结构)。

Finally, I settled on the vec function — it is quite fast, and was the right choice for handling DNA (essentially, the DNA is a bit vector, a built-in Perl data structure).

随后，此字符串将被传递给VectorSpace模块，并且数据散列的数据结构将依靠文件名来获得文件内的向量列表。

This string is then passed into the VectorSpace module, and a data hash data structure is keyed on the filename for the list of vectors within a file.
